Dodge / Ram
The majority of this information was contributed by Joe Schaefer, of the International Full Size Jeep Association.
The VIN is located on a plate mounted on the front door pillar of the left side door and is 12 digits long.
GVW Weights and/or Special Codes:
Sequential Serial Number:
Engine Code: (for '68-'71)
The remaining five digits are the sequential serial number.
Note: WB = wheelbase
Plant/Transmission/ Drive Code:
Body Style ('72-'74) :
The make was J for Jeep Corporation and the year was the last number of the year. For example, in 1972 the second number in the VIN would be 2. The 9th through 13th digits were the sequential serial number starting with 00001 and ending at 99,999. Beginning in 1974, body style was removed in order to make room for a six digit serial number. The first six digit sequential serial number began with 100,000. In 1975, the six digit serial number began with 000,001. In 1976, all wheelbases were shortened by 1". In 1978, all Toledo built vehicles' serial numbers started with 000,001 and all Brampton built vehicles' serial numbers started with 800,001.
Post-1980 Jeep VINs had 17 characters (the change was made to conform to Federal law). The 12th-17th numbers are a unique, nonsequential code.
(J = Jeep, B = AMC Canada Ltd.)
Type of car:
The model year started with B in 1981 and continued down the alphabet, skipping J, and ending with J in 1988. The serial number started with 000,001.
To protect the consumer from theft and possible fraud the manufacturer is required to include a "check digit" at the ninth position of the VIN. The check digit is used by the manufacturer and government agencies to verify the authenticity of the vehicle and official documentation. The formula to use the check digit is not released to the general public.
